Question

22 .The side of a square is 10cm. How many times will the new
perimeter become if the side of the square is doubled?​

Answer 1

Answer:

Twice or two times

Step-by-step explanation:

Side of square = 10 cm

Perimeter = 4 × side = 4 × 10 cm = 40 cm

New side of square = 2 × 10 cm = 20 cm

New perimeter = 4 × side = 4 × 20 cm = 80 cm

Therefore, the new perimeter will become two times the original perimeter.

Answer 2

Given:-

• Side of the square = 10 cm

To Find:-

• how many times will the new perimeter become if the side of the square is doubled.

Solution:-

As we are given with the side of the square = 10 cm

Let us first find the perimeter of the given side.

We know,

Perimeter of the square = 4 × side

Hence,

Perimeter = 4 × 10 = 40 cm

Now,

Since we have to find the perimeter when the side is doubled, hence,

Side = 2 × 10 = 20 cm

Now,

Let us find the perimeter of the new side,

Hence,

Perimeter = 4 × 20 = 80 cm

Now,

We have to find how many times did this perimeter become. To find that we need to divide the new perimeter by the original perimeter.

= 80/40 = 2 times

Hence the Perimeter becomes two times when the side of the square is doubled.

________________________________

How did I solve?

Firstly we were given the side through which we found the perimeter of the original square. Then we found the perimeter of the new square whose sides are doubled. Then as we were asked to find how many times does the perimeter become, we divided both the perimeters and found that the perimeter becomes 2 times.
